The present invention has reference, generally, to improvements in reflectors; and the invention relates, more particularly, to a novel construction of ventilated reflectorbody.

The present invention has for its principal object to provide a simple and etficien! construction of reflector holly adapted to he used to illuminateoperating tables, the said reflector body being provided with ventilating means whereby the heat generated by the illuminant is prevented from being concentrated upon the patient, the operating surgeon and attendants. Of course, it will he understood that the use of-such a novel reflector body is not. confined to operating tables. but that the same may he applied to many other The invention has for a further object to provide a inc-ans for carrying away from the interior of the refleetor-hmly the heatv gen.- erated'by the illiuninating units arranged therein, and at the same time providing a means for maintaining an insulating layer of cool air between the source of illumination and the locus to be illumii ed.

Other objects of the present invention, not at this time more particularly enumerated, will be clearly understood from the follow i mg detailed description of the present in vention. I

\Vtth the various olnects ()fllllS invention in view, the same consists. primarily, in the novel ventilated refieetonbody hereinafter set forth; and, furthern'iote, this invention consists in the novel arrangements and combinations of, theivarious mechanisms and. their parts, as well as in the details of th construction thereof. of which will hereinafter more fully described in the lowing specification, and then finally Specification of Letters Patent.

The invention is clearly illustrated in the accompanying drawings, in which V Figure 1 is a lon itudinalv vertical cross section of the nove construction of ventilated reflector-body made according to and embodying the principles of the present in vent-ion; Fi 2 is a bottom view of the same; and, ig. 3 is a transverse crosssection of the same takenxon line 33 in said'* Fig. 1. Fig. 4 is a longitudinal vertical cross-section of a slightly modified construction of ventilated reflect-or body embodying,- however, the principles of the present invention, there being illustrated in connec tion therewith, a means for creatinga forced circulation of air there/through,

Similar characters of reference .are employed in all of the hercinabove described views to indicate corresponding parts;

Referring now to the said drawings the 1 indiuitcs the complete reflector made according to and embodying the principles of the present invention, the same con'iprisiug a dome 2 from which (lcpendsa reflector-shell 3 terminating at its lower portion in a downwardly depending surrounding apron 4.

Supported by said partition memher 7 and extending downwardly through said interi r space 12 of said reflector shetl 12 are tu ular members 26, the lower ends of which project through properly disposed openings 27 in said partition-member or screen 16 so as to communicate with said intervening air-space or chamber 23. Said tubular members 26 communicate at their upper ends ivith said air-chamber 11 formed in the upper portion of said dome 2.

The ventilation of the reflector constructed as ahove described is accomplished as follows; The cool air from the exterior of the reflector p 'zsses through tlie air passagesfio into the intervening air space 23,121 portion the openings 17. i in said s'o reflected ilhtmina rise th pa s in capes Luv tioii ms:

I

Referring now more particularly to Fig. 4 of the accompanying drawings, there is illustrated therein a slightly modified construction of reflector enrnodying however. the general principles of the present inven tion. in this construction the reference character 28 indicates adorne. 29 the reflector shell. 3t th downwardly depending apron.

he reflector shell is provided with the ret ctor-niembers 31. Arranged within dome isuie horizontal partition-member from which depend the illuminating unis Arranged transversely beneath said refiectorshcll is the transparent partition member or screen 34. which, being shorter than the length of said reflector shell, provides an air passage 35kt each end thereof. The reference-character 36 indicatas aslidaioly disposed transparent partition member or screen. adapted to be registcred beneath said partition member or screen 34 to provide the intervening air-space The reference character 37 indicates the l'iandle-member of said partition member or screen 36.

The opposite end walls ,of said apron 30 are provided with suitably disposed series of holes r openings 39 com- :2.ndescentelec I by said partition member 32. Said ,partition-member 32 furthermore pro vided with suitably located holes or openings 43 providing air passages leading from the interior of said reflector shell into said air chamber 42 in said dome 28. The upper wall of said dome 2-8 is provided with an outlet passage or opening 44-. A hollow tubular hanger 4-3 is secured to said dome, and serves not only as a means for suspending the reflector, but, also, as a means for carrying away the heated air irom the interior thereof. Said hollow hanger 43 being provided with a T fitting, or other suitable device, it for connecting with said hollow tubular hanger 45 a pipe or duct 47 for corn \cying away the heated air. It will be understood that said tubular hanger 45 may be connected with a flue or chimney ot thc building in which the reflector is used whereby the circulation or draft is secured;

or, a suction fan or pump 48 may be connected therewith for drawing oil the heated air and establishing a forced draft through .--a id reflector. It will be apparent that the circulation of the air within this modified construction of reflector will take place as follows:-The outside cool air will flow' through said holes or openings 39 into said intervening air-space 38 and will be drawn upwardly through said tubular-members 40 nto said air chamber 42 and thence through said tubular hanger A portion of the cool air passing through said holes or openings 39 will find its way through said passages 35 into the interior of said reflectorshell 29, thence passing through saidholes (\I openings 43 of said partition member into said air chamber 42, and will pass thence thuough said-tubular hanger 45, thus establishing a circulation of cool air within said reflector-shell 29;

It will he clearly evident from the above description of the present invention that the same provides a novel ventilated reflector which will permit the desired character and quality of illumination. without the accomaniment of undesirable heat at the locus' 0' be illuminated. -be apparent, that the said reflector 1s partic- 'For thisfreason, it will ulgrly adapt-ed forthe purpose of illuminating operating tables in hospitals,.and'for the illumination of laboratory and other work benches. thereby preventing the heat from descending upon the persons working at such pla es, and '"liminating considcr able discomfort. and providing better working environment and conditions.

I am fully aware that some changes may be made in the general arrangements and combinations of the various devices and parts, as well as in the details of the construction thereof, without departing from the scope of the present invention as set forth in the foregoing specification, and as defined in the clauses of the claim which are appended to the same. Hence, I do not limit the present invention to the exact arrangements and combinations of the devices and parts described in the said specification, nor do I confine myself to the exact details of the construction of the said devices and parts as illustrated in the accompanying drawings.
